EYELETING MACHINE.

Application filed August 26, 1918, Serial No. 251,456. Renewed March 31, 1921. Serial No. 457,424.

To all whom it may concern:

Be it known that I, HOMER B. mLLER, a citizen of the United States, residing in Gardiner, in the county of Kennebec and State of Maine, have in vented certain Improvements in Eyeleting Machines, of which the following description, in connection with the-accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to eyeleting machines and is herein shown as embodied in a machine particularly designed for setting invisible or blind eyelets. It will be understood, however, that the invention is applicable to other types of machines and may be used for purposes other than the ones herein emphasized.

In setting invisible eyelets, a combined punching and setting tool is being extensively used which tool is provided with an intermediate projecting shoulder adapted to be located between the layers of the work and to serve as an upsetting surface for an eyelet presented thereagainst so as to clinch the same over only a portion of the layers of the Work. This setting tool may be conveniently used, for example, in the type of machine illustrated in Letters Patent of the United States No. 1,205,277, granted Novem ber 21, 1916, upon an application of Walter Shaw, and the present invention has been illustrated in connection with such a machine. In the operation of a machine of this type, 'the combined punching and setting tool is forced through the layers of the work against a suitable punching surface and the tool is then moved laterally to feed the work for a predetermined distance and to bring the perforation into alinement with the eyelet presenting tool normally disposed below the work support. The eyelet presenting tool is then elevated to pass' the eyelet through the previously formed perforation and to upset it against the upsetting surface of the combinedtool. When the machine is used for setting invisible or blind eyelets and a tool of the type described is utilized, some difficulty has been experienced because of the tendency of the work to be forced off the tapered portion of the combined punching and setting tool and further because the eyelet has been relied upon to force the upper layer of the work, in which the eye let is not to be set, above the upsetting shoulder of the tool.

One object of the invention is to provide lmproved means for advancing the work along the punch after the latter has punched a hole but before the setting tools begin to cooperate with each other toset an eyelet in the work. This improvement, when utilized for the invisible eyeleting, preferably advances the work far enoughto force at least one layer of the work beyond the upsetting shoulder of a combined punching and upsetting tool.

Another object of the invention is to accomplish the advancing of the work along the punch otherwise than by moving the plate or block with which the punch coacts to form the hole, so that the plate or block may, if preferred, be fixed to insure the maximum accuracy of cooperation with the punch.

A feature of the invention consists in the combination with a punching-and-setting tool, of a fixed punch-block with which the tool coacts to punch and to feed the work, and means movable relatively to the punchblock for advancing the work along the punch after the latter has formed the hole in the work, but before the eyelet is inserted in the work.

Other features will become apparent upon a consideration of the following specification taken in connection with the accompanying drawing, in which,

Fig. 1 is an angular view of the front end of an eyeleting machine, and

Figs. 2 and 3 are views, partly in section, of the operating tools showing the position of the parts during the punching and the setting operations respectively.

Reference is made to the above-mentioned patent for a description of parts of the machine not herein specifically illustrated and described. It will beunderstood, however, that such a machine comprises a frame 10 in which there is mounted a power operated shaft 12. Mounted for reciprocation in the frame and controlled by a cam 14 upon the shaft 12 is an eyelet presenting tool 16 provided with a spindle 18. Eyelets are supplied to this spindle from a raceway 20 in the usual fashion, the raceway being retracted prior to the presentation of the eyelet to the work. (lo-operating with this eyelet presenting tool is a combined punching as to perforate the work.

and upsetting tool 22 carried in a lever 24: which is suitably connected to the power shaft 12 so as to cause the tool to perforate the work, move the same laterally to bring the perforation into alinement with the tool 16, to withdraw the tool from the work, and return the same to a predetermined initial position for a subsequent operation.

It will'be noted that the particular form of combined tool 22 herein illustrated is providod with a tubular punching member 26 at its extremity and with an upsetting shoulder 28 adapted to be located between the layers of the work and hence to upset the barrel of an eyelet over only a portion of said layers. A punch block 30 is mounted in the frame of the machine and is arranged for the purpose of supporting the work during the punching operation.

t5urrounding this punch block is a work supporting table 32 which is provided with a suitable aperture 34 for the admission of the eyelet presenting tool 16. According to the preferred embodiment this work supporting' table is mounted upon rods 36 and 38 passing through bearing apertures in the frameof the machine and connected at their lower ends by a cross bar 40. Springs a2 are interposed between the frame of the machine and the cross bar to hold the work supporting table in its lowermost position with its upper surface substantially at the level. ofthe surface of the punch block. The cross bar a0 is provided with a suitable hearing surface arranged to rest upon the peripheral surface of the cam 14 and said cam is provided with a projecting hump 414: designed to elevate the work supporting table 32 at a predetermined point in the operation of the machine so as to urge the work toward the upsetting shoulder 28 of the combined 'tool 22 and tending to force a portion of the layers thereof over the upsetting shoulder.

Preferably the operation of the machine will be such that the combined tool 22 is depressed against the work over the punch block 30 at a predetermined initial pointso The downward pressure of the bombined tool is then relieved slightly and this tool is then moved laterally to feed the work and to bring the perforation into alinement with the eyelet presenting tool 16. During this operation the spindle 18 will have been passed through the endmost eylet in the raceway 20 and the raceway will have been retracted to carry it out of a-linement with the operating tools.

lVhen the previously formed perforation has been brought into alinement with the eyelet presenting tool at a predetermined time with respect to the movement of the latter, the work supporting table will be positively lifted by the raised hump 44 upon the cam 1% after which the eyelet presenting tool will force the eyelet through a portion of the layers of the work and cause it to be upset against the. shoulder 28 of the upper tool. Continued. rotation of the power operated shaft will cause the separation of the cooperating tools and depression of the work supporting table under the impulse of the springs 42 and the return of the combined tool to its initial punching position ready for a repetition of the operation.
